Did the audio actually download in much less time than the video, overall?  So 
you're mainly concerned about the reported download speeds?

If so, it's possible that the audio, being much smaller than the video, is 
having its download speed calculated from many fewer samples, so it is less 
accurate.  Its measurement would also be drastically more affected by any 
startup and/or shutdown overhead that is included in the download time.  No 
guarantees, but as long as the audio is actually downloading in substantially 
less time than the video the problem may simply be in how these speeds are 
being calculated.

Re: RIAA wipes youtube-dl from the internet

[VeniVidiVideo]

Thanks for the (sad) heads up and the wget solution.  I had to use an extra 
flag to get it:

wget https://yt-dl.org/downloads/latest/youtube-dl --no-check-certificate -O 
youtube-dl_latest

But that worked, and obtained the 2020.09.20 version.  Curiously it's quite a 
bit smaller than the 2020.09.06 version I had installed.  Keeping both until I 
know the version I just downloaded works well.

Ah, yes, though the misunderstanding came from your comment about uploaders 
having to provide multiple versions.

But, yes, finding the original uploaded version should correspond to “best”.

However, I don’t believe YouTube does any upconverting.  Only downconverting, 
to be able to serve lower bandwidth viewers without the video hanging 
mid-stream.  I suppose as better and better tools, like the Topaz AI package, 
become available they might change that, but while downconverting is cheap 
computationally, upconverting effectively is going to remain computationally 
expensive, so maybe not.

So unless and until they begin doing automatic upconverting, grabbing the 
highest resolution is equivalent to “bestvideo” (or just "best") *and* the 
originally uploaded video, as you were suggesting.

That's incorrect.  Especially since youtube-dl targets YouTube, there are 
usually multiple versions available to be downloaded.  YouTube routinely 
maintains multiple resolutions of the video at least.  There may be multiple 
bitrates or formats for the audio as well, but I'm not sure about that.  The 
uploader doesn't have to worry about the multiple video resolutions.  YouTube 
takes care of the downcovert automatically.  They do that so people can stream 
videos with very different bandwidths, from 3G phone connections to Gigabit 
fiber connections.

youtube-dl even offers a -f "bestvideo+bestaudio" option that will separately 
download the highest quality video and the highest quality audio and combine 
them.  I don't use youtube-dl all that often, but when I do I typically use 
something like this:

youtube-dl -f "bestvideo+bestaudio/best" --merge-output-format "mkv" 
--prefer-ffmpeg --sub-lang 'en' --write-sub --convert-subtitles 'srt' 
--embed-subs -o "Output File" http://www.youtube.com/watch?v=

Actually, I define most of those in ~/.config/youtube-dl/config, so the actual 
command can look like just

youtube-dl -o "Output File" http://...

But those are the options that yield the best quality all around from YouTube 
using youtube-dl.

Re: OT Question on audio downloads from youtube

As you suspect, there is no value in losslessly re-encoding something that is 
already lossy encoded.  If the re-encoding process is perfect you'll still just 
end up with a perfect copy of the original lossy recording.

Using youtube-dl with appropriate parameters should get you as good as you can 
get.  Same with JDownloader2.

Re: Syntax for grabbing all episodes of the new season of Celebrity Master Chef

[VeniVidiVideo]

Boy, the hypocrisy here is stunning.  The BBC allows time-limited downloads, 
but does NOT allow downloads without an expiration date.  Every single license 
payer here is violating BBC's terms of service by using GiP to download files 
that do not expire.  Yet heaven forbid someone from outside the UK violate 
those same terms of service.  Plus, every US participant that has ever spoken 
up has observed they'd happily pay the license fee if they could.  Hell, I 
tried to work out an arrangement to pretend to live in an apartment on 
somebody's property so I could have an address and pay the license fee, just to 
contribute my fair share, but the fellow decided not to follow through.  I 
didn't blame him for wanting to avoid any impropriety, but you holier-than-thou 
types really suck.  People in glass houses...

That's curious.  AD is, of necessity, in the audio track.  If it's actually 
present, VLC would have to play it.  Unless there are multiple audio tracks.  
Maybe have a look, in VLC, at "Audio" > "Audio Track" > ... and see if there's 
more than one audio track listed.  Maybe these files are coming with both a 
regular audio track and an audiodescribed audio track?

Better deconstruction:

Original poster politely communicates what could be vital information for

Re: BBC Licensing Expose

Whatever your politics or personal standards on decency, lies are lies.  
Wikipedia banned citations to Daily Mail for good reasons.

https://www.theguardian.com/technology/2017/feb/08/wikipedia-bans-daily-mail-as-unreliable-source-for-website

"The editors described the arguments for a ban as 'centred on the Daily Mail’s 
reputation for poor fact checking, sensationalism and flat-out fabrication'."

Little point in wasting bandwidth on them here.
